As far as I know, bitcoin payments take a little time to approve. Will these approval times make it difficult to use bitcoin in our daily lives?
For example, I would get a coffee from Starbucks. Do I have to wait for approval to pay for what I have done for hours?
I'd rather say using Bitcoin will be very clumsy for such ends
But you should first ask yourself why you would want to pay with Bitcoin for a cup of coffee (or tea). There is already fiat (cash) for that, and it will serve this purpose better. Since Bitcoin is rightfully considered better money than fiat while bad money always drives good money out of circulations, you will be just wasting good money on trivial things. Nevertheless, if you still want to spend your precious bitcoins this way, order a Bitcoin payment card and get done with that
